PROBLEM TO BE SOLVED: To solve such a problem that a funnelform body is easy to horizontally deform by forming a side face opening to let placed concrete or the like as a filling material flow out sideways at the side face of the funnelform body. SOLUTION: A side face opening 3 is formed to let placed concrete or the like as a filling material flow out to the side face side at the side face of a funnelform body 1. At first, while a required number of frame boards A are connected to each other lengthwise and breadthwise, the frame boards are laid on a specified ground surface. A filling material such as soil, concrete, etc., is poured into the funnelform bodies 1 from above the upper face, and at the same time, spreading work of rolling compaction using a roller is carried out. Excessive filling material is forced to run out of the side face opening 3 by the rolling compaction. As a result, the material assumes such a shape that it takes root in the ground. The lateral sliding movement of the funnelform bodies is restrained by the solidification of the outflow material S, and hence, a remarkable stable state can be kept.
